On Sunday night, the two former Disney stars were vying for MuchMusic Award’s Favorite International Artist/Group, and fans ended up voting Selena as the winner… Which didn’t settle well with Miley.

While she didn’t explicitly say what she was talking about, the “Wrecking Ball” songstress took to Twitter to express what appeared to be her dissatisfaction with the Canadian award shows’ voting system:

She could also be alluding to her loss against Lorde for International Video of the Year (which fans voted “Royals” instead of “Wrecking Ball”).

However, MuchMusic made sure to squash any rumors of “rigged” voting, tweeting last week: “Anyone saying our voting is ‘rigged’ should know that we have our own reliable tracking system.”

Meanwhile, Selena was incredibly excited over the big win, taking to Instagram to show her appreciation… Avoiding bragging rights over Cyrus, even though the “We Can’t Stop” singer threw some major shade at SelGo last week while performing her song “FU” in Milan.

What do you think? Was Miley being a sore sport? Sound off in the comments below!
